Dear Friend, Local changes can lead to cracks in the foreskin. The natural process of healing leads to local fibrosis, which leads to tight foreskin. This in turn makes it difficult to retract, and again development of cracks. And the cycle continues. Considering your age, it is best to meet a medical practitioner and have a complete examination to rule out causes like infection or any chronic condition. Circumcision, followed by pathological examination of the excised foreskin may be needed to help arrive at a definite diagnosis. Varad Sexology Clinic (Pune)
